    Abstract: In a continuous process for capping tubular filter elements, Fig. 2 (not shown) the caps 3 are fed in a series from a storage reservoir 2 to a stage 8 where a bonding agent e.g. thermosetting, themo-plastic resins and thermo-plastic binders, is ejected onto the caps from a dispenser 9. The bonding agent is uniformly distributed on the cap and maintained flowable by heating during transit over section 23 i.e. between stage 8 and a point D, where an operator pushes a filter cylinder firmly into the pool of bonding agent. The composites are fed over section 27, suitably heated to effect the curing of the bonding agent. On reaching an accumulation table 30, the composite is retrieved, inverted and the remaining open end of the tube is pushed into another cap, the seal being likewise effected. In a modification Fig. 1 (not shown), two assembly lines are provided. The rate of travel of the caps over the sections

    Abstract: An inertia filter is provided in which a high velocity flow of influent fluid is directed along the surface of the filter via a flow injector at a minimum velocity head loss of at least 2 psi across the flow injector. The inertia filter is positioned in a housing across the line of flow from the inlet to the outlet such that part if not all flow from the inlet to the outlet must pass through the inertia filter, and all flow to the outlet must pass through the inertia filter or another filter. The flow injector constrains and directs the flow at a selected surface portion of the inertia filter at high velocity of at least 20 ft./sec., in a manner to maintain an inertial flow component along the surface of the filter, to retain particles in the fluid and inhibit the lodging of particles on the filter surface. A sump is preferably provided in the housing to retain and collect contaminant particles swept along and off the surface of the filter, if the inertia filter is the only filter, but a sump is not needed if supplemental filters are provided in addition to the inertia filter.

    Abstract translation: 提供了一种惯性过滤器，其中流体流体的高速流动通过流动注射器沿着过滤器的表面以流动注射器至少2psi的最小速度头部损失被引导。 惯性过滤器定位在从入口到出口的流动线路上的壳体中，使得如果不是全部从入口到出口的流动必须通过惯性过滤器，并且到出口的所有流动必须通过惯性 过滤器或其他过滤器。 流动注射器以惯性过滤器的选定表面部分以至少20英尺/秒的高速度来限制和引导流体，以便沿着过滤器的表面维持惯性流动分量以将颗粒保持在 流体并且抑制过滤器表面上的颗粒的倒伏。 如果惯性过滤器是唯一的过滤器，则壳体中优选地设置有贮槽以保持和收集沿过滤器表面扫过的污染物颗粒，但是除了惯性过滤器之外还提供补充过滤器，则不需要贮槽 。
